Situated at a low elevation of 9 feet MSL, the airport provides critical aviation infrastructure for the Groton and New London metropolitan areas, supporting both general aviation and potential regional commercial operations.
Flying Conditions
The airport experiences predominantly VFR conditions, with 75.7% of observed weather periods suitable for visual flight rules. Wind patterns are consistently westerly at 270 degrees, averaging 9.3 knots with occasional gusts up to 41 knots. Temperature variations are significant, ranging from -14°C to 25°C, which pilots should consider for performance planning.
Notable Features
Both runways are asphalt-surfaced with substantial lengths: Runway 05/23 at 5000 feet and Runway 15/33 at 4000 feet. The coastal location suggests potential for rapidly changing weather conditions, with an average visibility of 9.3 statute miles and occasional periods of reduced visibility or fog affecting approximately 2% of observations.
Approach Considerations
Both runways demonstrate favorable wind alignment, with 100% wind compatibility for approaches. Average crosswind components are moderate, at 5.5 knots for Runway 05/23 and 6.3 knots for Runway 15/33. November, December, and September statistically offer the most consistent VFR flying conditions for pilots planning operations at this airport.
